Planar Non-inductive Power Resistor

The RESI HVLR Series is a high voltage thick film resistor designed for reliable operation in demanding high-voltage circuits. Built using thick film technology with advanced epoxy packaging, the HVLR Series combines high operating voltage capability with strong environmental durability. With resistance values from 1kΩ to 1GΩ, rated power from 0.7W to 15W and operating voltage up to 48kV, the HVLR Series supports a wide range of high-voltage applications. Its axial through-hole format provides robust mechanical integration, while the epoxy coating helps deliver excellent moisture resistance and reliable high-temperature performance. The series features a non-inductive design, low voltage coefficient of resistance and low temperature coefficient of resistance, helping maintain stable electrical behaviour in precision high-voltage circuits. Each resistor is subjected to 100% high-voltage testing after production, supporting dependable performance under high-voltage conditions.
